ABSTRACT

A façade structure and/or wall structure for a building which includes tiles (1) and a support structure (2), in which the tiles (1) are received oriented in each case in the vertical plane. The support structure (2) has taut tension elements (3). The tiles (1) received in the support structure (2) are mounted in a weight-supporting manner and/or held locked by means of one or more of the allocated tension elements (3), directly and/or via bearing bodies (4) attached to the tension elements (3). The several or at least one of the tiles (1) are or is allocated in each case at least one holding element (5). For anchoring to the tile (1), the holding element (5) has at least one anchoring portion that can be anchored in a receiver (1hn) of the tile, and/or cooperates with an anchor (6) received in a receiver (1hn) of the tile (1), and wherein the holding element (5) has at least one tension element gripping portion for gripping on at least one of the tension elements (3) allocated to the tiles (1).

The invention is based on a façade structure and/or wall structure for a building with the features of the preamble of claim 1.

Such façade structures and/or wall structures comprise a support structure with tiles received therein. The support structure has taut support cables. The tiles are held oriented in the vertical plane in the support structure with the aid of the taut support cables.

Such a façade structure is known from FR 669.554. The support structure of FR 669.554 is formed by vertical and horizontal steel cables, which have connectors at crossing points. At their vertical and horizontal outer edges the tiles have longitudinal grooves forming an overall circumferential outer groove in which the vertical and horizontal support cables engage. In addition, the façade tiles are supported in each case on two opposite corners on the connecting bodies arranged at the crossing points of the steel cables.

CN 2010 80660 describes a glass façade structure, wherein glass tiles are fastened to holders supported in a carrier structure. The carrier structure is formed of crossing vertical and horizontal steel cables. Holders of the glass tiles are fastened to the steel cables. To fasten the holders to the glass tiles, the holders pass through the glass tiles at the fastening points.

CN 1048 18790 describes a façade decoration system with a carrier structure, in which parallel steel cables crossing each other are braced in a frame. Hooks, on which tiles are held, are fastened to the steel cables.

DE 1 271 363 describes a façade tile system with a carrier structure with taut wire cables. The wire cables are exclusively vertically oriented, taut wire cables. These vertically oriented wire cables are fastened directly to the building wall at separate support brackets and hold the façade tiles, since the vertical wire cables run in longitudinal grooves formed on the vertical sides of the façade tiles or in vertical cavities. In this way, the vertical support cables each hold several façade tiles arranged one above the other, wherein in each case the lower corner and the upper corner of the vertically taut wire cable is fastened to an angled bracket.

Tile systems with flexible support structure are described in EP 2 154 302 B1 and EP 2 707 560 B1 as well as in EP 2 497 861 A1. In EP 2 154 302 B1 and EP 2 707 560 B1, the support structure is a flexible network of crossing, corrugated steel wires. The corrugated steel wires mesh with each other at the crossing points with their corrugations. The tiles each have longitudinal grooves on two opposite edges, in which the steel wires of the support structure engage. To fix the tiles, a mortar joint is provided for the wires running in the joint gaps. In EP 2 497 861 A1, the flexible support structure is formed in the manner of a chain framework, which is formed of horizontally taut parallel support cables, wherein in each case adjacent parallel support cables are connected to each other via connection elements. The parallel support cables pass through core holes of the tiles arranged in the support structure in such a way that the tiles are held on the horizontal support cables in the manner of chain links, with the result that the tile system represents a type of foldable curtain.

The object of the invention is to create a façade structure and/or wall structure of the type mentioned at the beginning which guarantees that the tiles are held securely in the support structure and is easy to install and inexpensive to produce.

This object is achieved with the subject-matter of claim 1.

The support structure 2 is represented only by way of example in FIG. 1 a. In the case represented, the support structure is made up of vertical support profiles 2 v and horizontal support profiles 2 h. The support profiles form a rectangular frame structure, in which the support profiles are connected to each other in the corners.

The support structure 2 is intended for a stationary installation, namely for example in front of a building wall outside or inside a building. For this purpose, the support structure 2 can in each case be installed in stationary bearings, not represented, supported on the floor side in the area of the lower horizontal support profile 2 h or on the roof side in the area of the upper horizontal support profile 2 h. Alternatively or additionally, the support structure 2 can also be installed supported correspondingly stationary laterally in the area of its left and right vertical support profiles 2 v, for example on adjoining building walls.

In each case taut support cables 3 are arranged in the support structure 2. In the embodiment examples represented in the figures, exclusively vertically oriented support cables 3 are present, and no crossing horizontal support cables.

In each case, the support cables 3 are fixed with their upper and lower ends in fastening bearings in the upper and lower horizontal support profiles 3 h.

The embodiment examples represented in the figures are façade structures or wall structures in which in each case large-format tiles 1 are mounted in a support structure 2.

The tiles 1 are preferably ceramic tiles. In the cases represented, the tiles 1 in each case have a rectangular outline and are produced in an extrusion process. Their dimensions are preferably more than 200 mm in horizontal length and more than 100 mm in vertical height. Much larger dimensions of the tiles are conceivable. As a rule, the support structure is story-high.

Reference is made to FIGS. 1b to 1d in the following:

The tiles 1 are mounted on the support cables 3. For this purpose, bearing bodies 4, on which the tiles 1 rest and/or through which the tiles 1 are locked in the support structure against pivoting out of the vertical plane, are attached axially fixed to the vertical support cables. The tiles 1 mounted in the support structure are arranged flush with each other in a common vertical plane. The common vertical plane is spanned by the support cables 3. The tiles 1, which are mounted on the support cables 3, are held in this plane by the bearing bodies 4 and by the support cables themselves, i.e. locked against pivoting out of this plane, which will be explained in even more detail.

In the cases represented, the bearing bodies 4 are formed in each case as spherical bodies. They are attached axially fixed to the vertical support cables 3, for example by welding the bearing bodies to the support cables.

On their left side edge and on their right side edge the tiles 1 have in each case an open longitudinal groove 1 vn, which extends along the vertical side edge of the tile in each case over the whole vertical extent of the tile, or of the side edge. These vertical longitudinal grooves 1 vn have a substantially U-shaped cross section. The left longitudinal groove is open towards the left end face and the right longitudinal groove is open towards the right end face. Furthermore, the longitudinal grooves 1 vn are also open at the ends of their longitudinal extent, i.e. at the top and bottom.

The vertical support cables 3 engage in the vertical longitudinal grooves 1 vn, since they extend in the longitudinal groove in the longitudinal direction and pass through upwards and downwards. The bearing bodies 4 attached to the vertical support cables 3 support the tiles in all four corners.

With regard to the supporting of the tiles 1 on the bearing bodies 4:

The weight-supporting mounting is effected primarily via the lower bearing bodies 4. In the area of their lower left corner the tiles rest, in each case in a weight-supporting manner, on a lower left bearing body 4 attached to the left support cable 3. In the area of its lower right corner the tile rests in a weight-supporting manner on a lower right bearing body 4 attached to the right support cable 3.

Upper bearing bodies 4 grip in the area of the upper left corner and the upper right corner, namely an upper left bearing body 4 attached to the left support cable 3 grips on the upper left corner, and an upper right bearing body 4 attached to the right support cable 3 grips in the area of the upper right corner. These upper bearing bodies 4 serve primarily to lock the tile in its vertical orientation in the common vertical plane against pivoting out of this plane. The lower bearing bodies 4 and the upper bearing bodies 4 are formed identically, i.e. in each case as spherical bodies.

In the cases represented, the tiles 1 do not cooperate directly with the bearing bodies 4, i.e. the tiles 1 do not lie directly on the lower and upper support bodies, but in each case on holding elements 5, which are mounted supported in the tiles 1.

The holding elements 5 in the embodiment examples of FIGS. 1b to 1d are formed as L bracket elements, which in each case are arranged inserted in the corner areas of the tiles 1. For this purpose, in addition to the longitudinal grooves 1 vn, which are formed along the left and right vertical edge of the tiles, the tiles 1 also have horizontal longitudinal grooves on the upper horizontal edge and on the lower horizontal edge, namely a horizontal longitudinal groove 1 hn open to the top on the upper horizontal edge, and a horizontal longitudinal groove 1 hn open to the bottom on the lower horizontal edge.

Like the vertical longitudinal grooves 1 vn, the horizontal longitudinal grooves 1 hn are also U-shaped in cross section and open at the ends of their longitudinal extent.

With regard to the design of the holding elements 5:

The holding elements 5 in the embodiment example of FIGS. 1b to 1d are, as already said, L bracket elements. They are formed as special U-shaped profiles. The distinctive feature of the special U-shaped profile is in each case that the U arms 5 u in a first longitudinal portion 51 of the U-shaped profile are longer than the U arms 5 u in a second longitudinal portion 52 of the U-shaped profile adjoining the first longitudinal portion 51. Specifically, the U arms 5 u in the first longitudinal portion 51 have the length L1. The U arms 5 u in the second longitudinal portion have the length L2. The length L1 is greater than the length L2, namely in the specific case the length L1 is approx. three times greater than the length L2. As can be seen from the figures, the longitudinal extent U1 of the first longitudinal portion 51 is shorter than the longitudinal extent of the second longitudinal portion 52.

In the side view of the U-shaped profile, therefore, a substantially L-bracket-shaped configuration results, i.e. the first longitudinal portion 51 of the U-shaped profile with the U arms 5 u of the length L1 forms the first L arm 5 s, and the second longitudinal portion 52 of the U-shaped profile with the U arms 5 u with the length L2 forms the second L arm 5 s.

The holding element 5 designed in this way is symmetrical with respect to the longitudinal center plane which runs between the U arms 5 u parallel to the extent of the U arms. This makes it possible to arrange the holding element 5 inserted in the tiles in all four corner areas.

In the area of the upper left corner and in the area of the upper right corner, the holding element 5 is arranged inserted in the tile, since the first L arm 5 s formed by the long U arms 5 u is pushed into the upper horizontal longitudinal groove 1 hn, namely forming a clamping connection to the insides of the longitudinal groove. The second L arm 5 s formed by the horizontal U arms 5 u is inserted in the vertical longitudinal groove 1 vn on the left and on the right side edge, respectively, of the tile 1. The free ends of the short U arms stand on the floor of the vertical longitudinal groove 1 vn, forming a receiving space for the vertical support cable 3 passing through the vertical longitudinal groove 1 vn. The receiving space for the support cable 3 is formed by the floor of the longitudinal groove 1 vn and by the space between the short U arm 5 u engaging in the longitudinal groove and the floor of the U-shaped profile.

The holding elements 5 inserted in the corner areas of the tile 1 thus guarantee a stable arrangement of the vertical support cables 3 passing through the left and right longitudinal grooves 1 vn of the tile. Furthermore, the holding elements 5 arranged in the lower left and right corner areas form bearings, with which the tiles rest in a weight-supporting manner on the bearing bodies 4 attached to the support cables 3.

The holding elements 5 arranged in the upper left and right corner areas are in contact with the upper bearing bodies 4 attached to the support cables. The bearing bodies 4 lie on the holding elements 5 inserted in the upper corner areas and thus lock the tiles in their position against pivoting out of the common vertical plane, in which the tiles are arranged flush with each other in the support structure.

The embodiment example of FIGS. 2a to 2c is an embodiment example modified compared with the embodiment example of FIGS. 1a to 1 d. The modification consists of the fact that in the embodiment example of FIGS. 2a to 2c the L-bracket-shaped holding element 5 cooperates with a separate anchor 6. The anchor 6 is formed as a double-T-shaped profile, which is arranged in the horizontal receiving groove and cooperates with the horizontal L arm of the holding element 5. The cooperation consists of the fact that the right end of the anchor 6 represented in FIGS. 2a to 2c cooperates with the right holding element 5. With the left end of the anchor 6, not represented, which extends over the whole longitudinal extent of the tile in its horizontal groove, the anchor 6 cooperates with the left holding element 5, which is arranged in the left corner of the tile. The cooperation of the right end of the anchor 6 with the right holding element corresponds to the cooperation of the left end of the anchor 6 with the left holding element. The holding element 5 is modified compared with the holding element 5 in the embodiment example of FIGS. 1a to 1d to the effect that on their outside the long U arms, which are arranged engaging in the horizontal receiving groove 1 hn of the tile, each have a row of saw-tooth-shaped teeth parallel to each other. Here, the parallel teeth extend in each case transverse to the longitudinal extent of the longitudinal groove 2 hn. On its represented right anchor end, and in the same way on its not represented left anchor end, the anchor 6 has leaf spring mechanisms, which have leaf springs with bent end edges, which engage in the row of saw teeth on the outside of the two U arms of the holding element 5, namely gripping on the steep flank of the respective tooth in the manner of a gripping from behind.

The double-T-shaped profile has a connecting arm, at the ends of which in each case a transversely running T arm is formed. The double-T-shaped profile is arranged in the horizontal longitudinal groove 2 hn such that the connecting web is oriented vertically and the transverse webs are in the horizontal plane, i.e. parallel to the floor of the horizontal longitudinal groove 2 hv with the U-shaped cross section. The double-T-shaped profile is arranged with its vertically running connecting web engaging between the U arms of the holding element 5. The spring mechanism 6 f consists of two leaf springs, which form a Y configuration. The Y arms are fixed with their base portion on the double-T-shaped profile in the area of the vertically oriented connecting arm by a common fastening mechanism. The two Y arms are arranged between the lower and the upper transverse web, namely one Y arm on the left side of the connecting web and the other Y arm on the right side of the connecting web. With its chamfered free end the left Y arm cooperates with the row of saw teeth on the outside of the left U arm of the holding element 5. With its free chamfered end the right Y arm cooperates with the row of saw teeth on the outside of the left U arm of the holding element 5. At the not represented left end of the anchor 5, the left anchor end cooperates in the same way with the U arms of the allocated left holding element 5, i.e. the anchor is anchored with its right anchor end to the right holding element 5 and with its left anchor end to the left holding element 5. The two holding elements 5 are thus braced with each other via the anchor 6. Through this bracing of the two holding elements 5, the allocated vertical support cables 3, which pass through the vertical longitudinal grooves 2 vn on the right and left tile edges, are braced with each other, as the right vertical support cable passes through the receiving space which is formed between the U arms of the vertical L arm of the right holding element 5, and the left vertical support cable passes through the receiving space which is formed by the U arms of the vertical L arm of the left holding element 5.

The two holding elements 5 arranged at the lower corners of the tile, namely the lower right holding element 5 and the lower left holding element 5, are braced with each other via an anchor 6 received in the lower horizontal receiving groove 2 hn in the same way as the two upper holding elements 5 and correspondingly brace the two vertical support cables in this lower horizontal area.

In the embodiment examples in FIGS. 3a to 3b , the holding elements 5 are formed deviating from the previously described design. The holding elements 5 in FIGS. 3a to 3b are formed as elongate, clip-shaped elements which extend axially, i.e. slightly curved substantially in an axial direction. Two such holding elements 5 are inserted in the upper horizontal longitudinal groove 1 hn of the tile 1 in FIGS. 3a to 3b , namely in such a way that the main longitudinal portion of the holding element 5 is arranged extending longitudinally in the left horizontal longitudinal groove, and that the free end of the holding element 5 protrudes into the left vertical longitudinal groove and there grips the vertical support cable 3 passing through the longitudinal groove from behind by means of a hook-shaped end formed on the left end of the support element 50. The right holding element 5 is arranged correspondingly in the right portion of the upper horizontal longitudinal groove 1 hn and engages in the right vertical longitudinal groove with its free right end. The hook-shaped free right end grips on the support cable 3 guided through in the right vertical longitudinal groove. In a corresponding manner, two such holding elements 5 are arranged in the lower horizontal longitudinal groove 1 hn. The left holding element is arranged with its main longitudinal portion in the left half of the lower horizontal longitudinal groove 1 hn and engages in the left vertical longitudinal groove with its free left end, wherein the hook-shaped free left end grips on the vertical support cable 3 guided there. In a corresponding manner, the right holding element 5 rests in the right half of the lower horizontal longitudinal groove 1 hn and grips on the vertical support cable, which passes through the right vertical longitudinal groove, with its hook-shaped free right end.

The anchoring of the holding elements 5 in the tile 1 is effected by the curved shape of the main longitudinal portion of the holding element 5 via elastic clamping connection to the inner wall of the horizontal longitudinal groove. The curved shape is formed such that the main longitudinal portion of the holding element 5 can be pushed into the horizontal longitudinal groove only under elastic deformation and the elastic clamping connection to the inner wall of the longitudinal groove is formed there.

The free ends of the holding elements 5 gripping on the vertical support cables 3 cooperate with the bearing bodies 4 attached to the support cables. In the case of the holding elements 5 arranged in the lower horizontal longitudinal groove 1 hn, the free end which grips on the allocated vertical support cable 3 rests on the bearing body attached to the support cable, with the result that the weight forces of the tile 1 are introduced onto this lower bearing body 4. In the case of the holding elements 5 arranged in the upper horizontal longitudinal groove 1 hn, the free end which grips on the allocated vertical support cable 3 rests, in contact, on the underside of the bearing body 4 attached to the support cable 3, with the result that the arrangement of the support cables 3 passing through the vertical longitudinal groove, and thus the position of the tile, is stabilized and locked by the bearing body 4.

FIG. 4a shows modified holding elements 5 for an embodiment example modified compared with FIGS. 3a to 3b . In the modified embodiment example of FIG. 4a , unlike the holding elements in FIGS. 3a to 3b , in each case only one holding element 5 is arranged in the upper horizontal longitudinal groove and one holding element 5 is arranged in the lower horizontal longitudinal groove. The holding element 5 corresponds in terms of its axial length to the whole longitudinal extent of the tile 1 and thus to the whole longitudinal extent of the horizontal longitudinal groove in which the holding element 5 is received. In the case of its arrangement in the longitudinal groove, its free left end engages in the left vertical longitudinal groove 1 vn and there grips on the left support cable 3 guided through this vertical longitudinal groove. Its free right end engages in the right vertical longitudinal groove 1 vn and there grips on the right support cable 3 guided through this vertical longitudinal groove. The anchoring of the holding element 5 in the longitudinal groove is effected by the curved shape of the main longitudinal portion of the holding element formed between the free ends. The anchoring is thus effected in a manner corresponding to that in the case of the previously described holding elements, namely likewise through an elastic clamping connection of the curved main portion of the holding element pushed into the longitudinal groove. Also in the case of these holding elements 5, the bearing bodies 4 attached to the vertical support cables 3 act in the same way on the tiles via the holding elements 5, i.e. the lower bearing bodies 4 primarily act in a weight-supporting manner, and the upper bearing bodies 4 act in the manner of a stabilizing and locking of the position of the tile against a pivoting of the tile out of the common vertical plane in which the tiles 1 arranged in the support structure are flush with each other.

In FIG. 5a the vertical support cables 3 are arranged in the support structure such that in each case a few separate left and right vertical support cables 3 are available for in each case horizontally adjacent tiles of a row. This has the result that horizontally adjacent tiles of a row can be arranged adjoining each other relatively closely depending on the arrangement of the vertical support cables. The arrangement of the six vertical support cables in FIG. 5a is as follows in the order from left to right:

-   -   First vertical support cable spaced apart from the second         vertical support cable with spacing: tile length of the left         tile     -   Second vertical support cable spaced apart from the third         vertical support cable with spacing: minimum spacing     -   Third vertical support cable spaced apart from the fourth         vertical support cable with spacing: tile length of the middle         tile     -   Fourth vertical support cable spaced apart from the fifth         vertical support cable with spacing: minimum spacing     -   Fifth vertical support cable spaced apart from the sixth         vertical support cable with spacing: tile length of the right         tile.

The spacing of the horizontally adjoining tiles is determined by the minimum spacing. In the case of the use of bearing elements 4, on which the tiles rest, received axially fixed on the support cables 3, this minimum spacing is determined by the diameter of a bearing body 4, or the minimum spacing is determined by the minimum receiving depth with which the vertical support cables have to be received in the vertical longitudinal groove 1 vn in order to guarantee a stable hold of the tiles in the vertical plane spanned by the vertical support cables.
